Object reference not set to an instance of an object

Whenever I try to create a new flowchart or sequence, I get this error “Object Reference not set to an instance of an object”.

Also when I try to open an existing project I get an error “Workflow Designer encountered problems with your document”.

Please help.

Hi @Pratik

You need to provide default value to the variable.
Use debug and check for the variable which needs default value.

I believe this error occurs mostly when UiPath runs out of memory space.
Close all instances of Studio and open a fresh one.

Hi
Please reinstall the packages through “manage packages”

Hi Rajkumar,

I uninstalled and re-installed all the packages but still the problem persists. Do you have any other approach ?

Thanks

Hi Rahamtullah,
“Object Reference not set to an instance of an object” I am getting this error when I try to create a new sequence or workflow.

“Workflow Designer encountered problems with your document” I tried restarting the studio multiple times but with no effect.

Can you think of any other solutions?

Thanks

Hi @Pratik,

“Object Reference not set to an instance of an object” - Can you please
share the workflow.

“Workflow Designer encountered problems with your document” - For me this
error got resolved after restarting Studio. There might be other
resolutions as well which other members on the forum can suggest.

this is a very common and generic error that means you are trying to use an object that has no value yet, for help we will need to see some activity code…

is this workflow file your real one or example? there are activities loose in there and arrow that goes for two ways… there are so many errors that i dont know where to start the help :frowning:
